$(a)$ Draw a diagram of the human alimentary canal and label the gall bladder, liver, and pancreas.
$(b)$ State the roles of the liver and pancreas in digestion.
$(c)$ Name the organ that performs the following functions in humans:
$(i)$ Absorption of digested food.
(ii) Absorption of water.

(N/A) Refer to the provided diagram.
$(b)$ Roles of organs:
- Liver: It produces bile juice, which is stored in the gall bladder. Bile salts help in the emulsification of fats, breaking large fat globules into smaller ones to increase the efficiency of enzyme action.
- Pancreas: It secretes pancreatic juice containing enzymes like trypsin (for protein digestion), lipase (for fat digestion), and amylase (for carbohydrate digestion).
$(c)$ Organs performing the functions:
$(i)$ Small intestine: The inner lining of the small intestine has numerous finger-like projections called villi, which increase the surface area for the absorption of digested food.
(ii) Large intestine: The primary function of the large intestine is the absorption of water and salts from the undigested food material.
